Sierra 10.12.2 frequent system freezes

Could make a book out of all the console error messages (erros and failures). No fun reading.
most common fatal failures i suspect are the sandbox errors core issues like coreaudio, some internet related stuff, contacts. Mostly the system runs oke, but on video playback (public streams, also youtube) the party begins. I did all the ussual noob handling (safe mode, pram, cache emptying, re install, clean install) but i suspect i need to get into the comandline to really fix things. I've seen some wild fixes by people, but i dont really want to go there. time?
So i'm just curious if there are other folks out there waiting for the big bugfix update sys. and or enlighten me any other way. not since sys 7, 8 or 9 have i rebooted so many times. And i did skip el capitan!

I don't have solution for you, I'd just like to share with you that I had some brutal hard freezes (audio would play but everything else just froze indefinitely) on ElCap 10.11.6 and Sierra 10.12.0-10.12.1 and only installing 10.12.2 beta fixed it completely. MacOS is highly idiosyncratic if you have a big stability issue like this, you don't really have nothing to lose by installing a beta. Try that, it MAY help.

Got my mbp mid2010 so it's getting older, but this is by far the worst OS I've had on it. Almost forcing me to get a new one, it's that bad. Constant beachballs and freezes. Remember when this thing was light and snappy.

I have had some system freezes too on my iMac 27", but they were already present in El Cap. They were difficult to diagnose, since the console didn't give much relevant information. But disabling WebGL in Safari fixed the issue for me. Mac hasn't crashed since.
